COPS found 13 children shackled to beds in their dirty home in California in a shocking discovery.
The two parents have been arrested following the disturbing find – but what do we know about them and the children?
David Allen Turpin, 57, and Louise Anna Turpin, 49, were arrested and charged with nine counts of torture and 10 counts of child endangerment.
The arrests were made after one of the 13 siblings called police and said her 12 brothers and sisters were being held captive.
She was so emaciated cops thought she was 10 years old at first.
The 17-year-old told police some of her siblings were bound with chains and padlocks.
Police said when they arrived at the property in Perris, about 70 miles east of Los Angeles, they found children shackled to their beds in "dark and foul-smelling surrounds".
The shocking discovery was made on January 14 in the US state.
A statement from the Riverside County Sheriff's Office said: "Deputies located what they believed to be 12 children inside the house, but were shocked to discover that seven of them were actually adults.
"The victims appeared to be malnourished and very dirty."
Neighbours told local media they had no idea there were children in the house, while others said they only saw them at night.
The six children were transported to the Riverside University Hospital System (RUHS) for medical examinations and admitted for treatment. The seven adult children were taken to Corona Regional Medical Centre for an examination and treatment.
Pictures were later made public which showed an unkempt garden, dirty carpets and doors with scratches on.
David Turpin's parents, James and Betty, from West Virginia, said they were "surprised and shocked" at the allegations.
After the pair's arrest pictures emerged of them and the 13 children posing on various day trips.
One showed the couple and the kids at Disneyland, wearing matching T-shirts.
Another showed the Turpin's getting married in a Las Vagas style ceremony – complete with Elvis impersonator.
The children were gathered around the couple wearing matching dresses and suits.
The girls all had matching hair cuts and the boys all sported bowl cuts.
The family were said to be big fans of Disneyland and went on holidays to the theme park.
Some residents said they saw the kids picking up rubbish around their home and digging for food in bins, according to CBS2 News.
Neighbours have also told how they would rarely see the children – with one claiming to have been unaware there were any living at the house.
Andrew Santillan, who lives around the corner, told the Press Enterprise: "I had no idea this was going on. I didn't know there were kids in the house."
Neighbour Andria Valdez said her family had joked the Turpins reminded them of the family of vampires from the Twilight book and film series.
The aunt of the kids told Good Morning America when she lived with her sister and brother-in-law she felt uncomfortable with Mr Turpin's alleged behaviour towards her.
The parents are due in court on January 18.
